Any success stories with CAN bus on PDS?

I just looked in the datasheet, I think youre right Bob. I've only been doing this for 2 days, so lots to learn still

Hi, its great to see you visiting our forum. Why not try Proton Compiler for FREE? Download the FREE version of Proton Compiler, Its called Amicus18 and its available from HERE Already using proton Compiler??? Get rid of these pesky messages... get LICENSED USER STATUS

You could try, I never have as I do not think it will be stable, I use 40Mhz osc modules.

Hi Bob,
I've used your code above with a 18F4580, and it works like a dream. I tried to port it over to 18F46K80, with no joy. I get an led toggling in the main code, but not in the interrupt. If I understand it correctly, I should get an interrupt from the timer overflow, even if the CAN isn't working?

If PIR1.0 = 0 Then GoTo CAN_MODULE_INTERRUPT 'TIMER1 INTERRUPT FLAG
Clear T1CON.0 'Stop timer
TIMED_TRANSMIT_ROUTINE: 'If it wasn't the CAN module it must have been the timer Interrupt
Toggle LATC.6 'Flash RED LED just to let me know it is doing something

I've found some of my problem. Most of the 18F46/66K80 CAN interrupt flags are in PIR5. On the 18F458/4580 they're in PIR3 (as Bob's example above)

Also the ERRIE and RXB0IE are in PIE5 on the 18F46/66K80.

Hi John,
Glad you have it sorted, I cannot help much at the moment as I am in a foreign country (Scarborough), at least I think I am as I cannot understand the locals.
Can't be that bad though, can only get WIFI in the bar.

Bob
